Help On Speech Assignment

[john]

I have to give a speech on anything I want on wednesday. It has to be ~6 minutes and I have to include 3 sources. I can do a informative, a persuasive, someone I admire, etc. No guide lines. The problem is I cannot figure out what to do. I am not creative at all. I want to do something unrelated to cars as all of my other speeches were about them. I want a funny topic. Any ideas on what I should do? Thanks in advance, John.
